APPARATUS FOR CLEANING THE RESIDUUM FROM ZINC-RETORTS.

SPECIFICATION forming part of Letters Patent No. 319,270, dated dune 2,18815.

Application filed January 12, 1885. (No model.)

To all whom it may concern:

Be it known that We, WILLIAM LANYON and ROBERT H. LANYoN, both citizensof the United States, and residents of Pittsburg,

Crawford county, Kansas, have invented certain Improvements in Apparatusfor Cleaning the Residuum from Zinc-Itetorts, of which the following isa specification.

' Our invention consists of apparatus, fully described and claimedhereinafter,I for cleaning the residuum from zinc-retorts prior torecharging the same.

In the accompanying drawings, Figure 1 is a front view of abench ofzinc-retorts with the 'suspended deie'cting-shield in front of the same,and Fig. 2 an enlarged sectional perspective view illustrating ourinvention.

Referring in the rst instance to Fig. 2, A is part of the brick-work ormasonry in which a series of retorts, B, are built, one only of theseretorts being shown in this figure.

In front of the bench of retorts is a movable shield, D, moreparticularly referred to hereinafter, ,this shield having a number ofopenings, c.

A portable pipe, G, can be passed through any one of the openings in theshield and into any one of the retorts. This pipe terminates at one endin a suitable nozzle, b, and being closed at its outer end, butcommunicating near the latter through a eXible pipe, II, with asteam-generator.

The attendant having introduced a portion of the pipe into the retortlets on the steam 3 5 by manipulating any appropriate valve with whichthe pipe may be furnished, and the consequence will be the injection ofa forcible jet of steam into the retort. The steam will of courserecoil, and the result will be the expul- 4o sion from the mouth of theretort of the residuum which had been left in the same, this residuumstriking the shield by which it is deflected onto the fioor of theretort-house, or into a pit, w, made in the floor in front of the 45bench of retorts.

The operator can so move the pipe about that the steam may be directedto all parts of the retort. The shield protecting him from the iiyingresiduum which is generally in a 5o red-hot condition.

,As particles of rcsiduum might find their way through the opening a inthe shield and interfere with the comfort of the operator, we prefer toattach to the pipe a guardplate,W, of sufficient size to deflect suchparticles as may pass through the said opening in the shield.

In Fig. 1 we have shown the front of the bench of retorts, the latterbeing in the present instance in five horizontal rows, eleven retorts ineach row, and the shield D being as long, or nearly so, as the bench,and having an opening, a, for each retort in a row.

The shield may be constructed and arranged in different ways in carryingout the invention. In the present case it is suspended to two iron ropesor chains, h h, one near each end of the shield, and is suitablyconstructed so as to be easily raised and lowered, adjusted opposite tothat row of retorts which has to be operated on, and, nally, elevatedout of the way when the whole of the retorts have been cleansed. Thisplan we prefer; but it is not necessary that the shield should becoextensive longitudinally with the bench of retorts, or that it shouldbe a suspended shield. It may, for instance, be more contracted inlength and may be arranged to be moved on rollers over the floor of theretort-house; hence we do not desire to confine ourselves to a movableshield of any speciiic construction.

We are aware that it has been proposed to construct a gas-retortdischarging device con` sisting of a ,steam-pipe carrying a shield toprevent the heated contents of the retort from striking the workman whenhe manipulates the pipe; but if the shield is made so large and heavy asto effect this result in our apparatus the pipe cannot be manipulated asit should be; hence we employ the main shield D supported independentlyof the pipe and perforated for the passage of the latter, the onlyshield carried by the pipe being the light disk WV for shielding theworkman from any particles which may pass through the perforation of themain shield.

We therefore claim as our invention- 1. The combination of a bench ofzinc-retorts, a portable pipe constructed for introduction into theretorts and communicating` through a flexible pipe with asteam-generator, and the shield D supported independently IOO ofthe pipeandI perforated for the passage of names to this specification in thepresence of the latter, as'set forth. two subscribing Witnesses.

2. The'combnation of the pipe G, communioating with a generator andhaving a guard- WILLIAM LANYON.
